Base on the platform of GIS, adopting three-dimensional visualization technique, the methods of realization for the construction of three-dimensional visual digital models and dynamic simulation of construction process of hydroele ctric engineering construction system are presented in this paper. Firstly, the principles of GIS-based three-dimensional visualization are elaborated in the pa per. Secondly, the methods of the construction of three-dimensional visual digit al models are discussed. Then, the digitizing technique of terrain, the modeling technique of static geometric objects, the modeling methods of dynamic entities , and the approach of dynamic simulation for construction process are introduced in details. Finally, several examples of engineering application are showed to prove the effectiveness and practicability of this method.
